Abstract

Fig. 1 shows an integrator network in which the discharge current always equals the charge current so that the output triangle is always proportional to the input. Fig. 2 shows the waveforms at the indicated points in Fig. 1. The operation is as follows: The input signal 1 and the delayed and attenuated signal 2 are combined by the difference amplifier to produce output signal 3 which drives the integrator consisting of an RC network. At T0 time, a +1 volt applied to the integrator charges the capacitor to +0.63 volt. At 1TC time, the amplifier output switches to -0.37 volt level, creating a 1 volt discharge potential (same as the COMPENSATED INTEGRATOR - Continued charge potential).
